esm2_t30_150M_UR50D

ESM-2 is Meta's protein language model trained on UniRef50, treating amino acid sequences analogously to text tokens. The t30_150M variant has 30 transformer layers at 150M total parameters, offering a practical balance between representation quality and inference speed. ESM-2 embeddings are widely used as features for protein function prediction, structure-adjacent tasks, and zero-shot fitness scoring.

Last reviewed

Use cases

  • Extracting fixed-length protein sequence embeddings for ML classifiers
  • Zero-shot scoring of amino acid mutations for fitness prediction
  • Featurising sequences for binding site prediction models
  • Pre-training initialisation for domain-specific protein fine-tunes
  • Benchmarking representation quality across ESM-2 model sizes

Pros

  • Trained on 250M UniRef50 sequences; broad coverage of protein space
  • Multiple model sizes released with consistent API for easy scaling experiments
  • Well-cited in structural biology and protein engineering literature
  • PyTorch and TF weights; endpoint compatible

Cons

  • Masked language model; generates embeddings not sequences
  • Outperformed by ESM-3 and ESMFold on structure-adjacent tasks
  • 150M may underfit very diverse protein families compared to 650M+ variants
  • Requires biological domain knowledge to interpret outputs meaningfully

When does esm2_t30_150M_UR50D fit?

Picking a fill mask model means matching esm2_t30_150M_UR50D's declared task to your specific input distribution. Public benchmarks rarely predict downstream behaviour, so treat esm2_t30_150M_UR50D's reported numbers as a starting point, not a verdict.

  • You're picking a fill mask model for production → esm2_t30_150M_UR50D is a candidate, but always validate against your own evaluation set before committing — public benchmarks rarely predict downstream task performance.

Real-world usage signals

Specific to this card: The card advertises one-click deploy to azure, if you would rather not manage the serving layer yourself.

10 likes from 483,383 downloads suggests esm2_t30_150M_UR50D is mostly being tried, not adopted. Common for newer releases or pipeline-specific tools that have a narrow target audience.

10 tags — esm2_t30_150M_UR50D is positioned for a specific bundle of related tasks. Likely a strong fit for the named use cases and weaker outside them.

Publisher information is incomplete on the model card. Cross-reference esm2_t30_150M_UR50D against the GitHub repo or paper before treating provenance as established.

How we look at fill mask models

esm2_t30_150M_UR50D has crossed the threshold from "experiment" to "actively-used" on HuggingFace. The community has enough hands-on experience that you can find real deployment reports, but not so much that esm2_t30_150M_UR50D is a default choice in this category.

Download count alone is a thin signal — it conflates "people trying it" with "people running it in production." For esm2_t30_150M_UR50D specifically: 483,383 downloads — solid usage, but you may need to read source code rather than tutorials when something goes wrong. Pair that with the engagement read above, the date of the most recent issue activity, and a 30-minute trial run on your own evaluation set before deciding whether esm2_t30_150M_UR50D earns a place in your stack.

Frequently asked questions

Can I use esm2_t30_150M_UR50D commercially?

mit is a permissive license, so commercial use including modification and distribution is allowed. Read the actual license text on the model card to confirm — license tags can be misapplied.

Is esm2_t30_150M_UR50D actively maintained?

483,383 downloads — solid usage, but you may need to read source code rather than tutorials when something goes wrong.

What should I check before depending on esm2_t30_150M_UR50D in production?

Three things: (1) the license text — assume nothing from the tag alone; (2) the most recent issues on the HuggingFace repo to gauge how the maintainers respond to bug reports; (3) reproducibility — run the model card's stated benchmark on your own hardware and confirm the numbers match within 1-2%. Discrepancies usually mean different precision or a tokenizer version mismatch.
